Shame on me for posting again in this ridiculous thread but wrt the two current F30-s the dominant constraint in normal driving for those with turns and curved roads is handling not acceleration. Which is why reported track times are so similar.

This was a load bearing dyno, not the inflated numbers of a Dynojet(245-250whp/280tq is a good Dynojet estimate):

Thanks! Looks very promising.

Forgot to ask, was this dyno with the exhaust only?

It seems like the turbo is running out of air towards the end of the powerband. Perfect candidate for cams and fuel compensation such as a piggyback tune. Turbo upgrade would also cure the flat curve of the HP powerband.

About all they would do for you is a F30 specific stealth subwoofer enclosure.

IA is doing a sub-box, but also all components and amps, the headunit is left appearing stock and full functional. It's going to be about $4k in audio installed. I really lucked out. They also gave me a loaner while they had my car. It was an '01 Explorer Sport, but still really convenient.

I'll take a free stealth box lol. THey were going to do work on my E90 335 a few years back but our schedules never matched up

Can you please remove the title of this thread?? I'm tired of looking at it every time I turn on the forum of our BMW fan site. Maybe you should buy a 1978 Cadillac or something to get a real underwhelming boat. Thanks.

It hurts me to say that the 328i feels like an undwhelming boat.
I'm not terribly disappointed because its a beautiful luxury car.
But I don't think it's the ultimate driving machine.
Maybe the 335i is, but I've not driven it so I can't say for sure.
Already planning to get a Z4 or the new Boxster for thrillfull driving.
Hate me for saying all this.
But I simply had to say it.
And I gave it a week.
Maybe I'll feel differently in a month.
But maybe that will be cuz I might have got used to this 328i by then.

If you filter the whining and banter from this thread we've actually changed the OP's mind with useful posts.

Such as proper settings to enhance the driving modes- sport.

Then expectations with the F30 chassis. No it's not a mini and it's definitely not the same as the older E46 or E9x chassis.

We've also provided links to BMW M performance upgrades. These upgrades (brakes, suspension, engine, exhaust) do get you closer to the older chassis.

Err not sure you changed his mind but you probably made him more aware that the 328 can do more then he expected. What I seem to read was that he wants a 335 now and given what he wants out of a BMW, that's what he should have bought to begin with and this 46 page odyssey would never have been spawned.

BJ btw I thought of you every time I saw a $200K 7-series on vacation in New Delhi. Thinkin they coulda been smart like you and just bought 3-series instead. Save $$$ and probably easier to drive on those super crowded roads.
